Plant Deficiency? Mg? Over Fert ? Pic inside!

Hello, I have been vegging this clone for about 3 weeks & recently the leaves started to twist slightly & have began to turn yellow on the outside of the leaf with little brown spots. I've been doing a little research & it looks to be the most similar to a Mg deficiency or Over Fert. or maybe even heat stress but I would like to know for sure ! Also I have 3 other clones right next to it same distance from light, same nutes, & 1 of them is the same strain. Thanks to anyone who replies : ) & sorry for bad quality, it's a cell phone

Try a bigger pot and just give it water for a few days or maybe you are in need of micro nutes depending on the soil you use.

I don't think its a container issue. I just transplanted today into 1 gallons & they weren't near rootbound. What micro nutes are you referring of ? I'm using MG potting soil ( yess i know -___-) because I have 2 bags laying around that needed to be disposed of. I mixed it 50/50 with Perlite to get a less concentrated medium.

Bump. Please I need help, I was reading around some more & it seems like people are having problems with MG soil having PH problems that cause nute lockout. I was wondering if that could be my problem ? I read that Magnesium is the first to get locket out, so I figured this might be a deficiency cause by nute lockout from incorrect Ph? Could I be right ? & what would be the easiest fix, dolomite lime?

Someone told me to grab some dolomite lime and sprinkle some over the topsoil according to what the bag says. BUT I dont know from actual experience how much to give. And I still believe water ph testing is required, pre-water and runoff.

this link is pretty helpful to identify some issues, has pics to go by, yours kinda looks like the early stage of Calcium Deficiency. You notice how the MG def is yellowish with the spots, and the Calcium has the spots but is still a darker green, like your pic is
